Crimes: Murder, infanticide, cowardice, arrogance, petulance, sociopathic behavior
Most evil moment: Ordering the murder of all of Robert’s bastards (even infants) so there was no challenge against him for the Iron Throne.
Out of many villains in The Game of Thrones, Joffrey is one of the most hated characters. During his reign, he spends most of his rule hitting women or by ordering others to do it on his behalf. The sociopath enjoys shooting people with his crossbow for fun and he has no problem ordering the murder of his half-brothers and sisters who could potentially lay claim to the throne. It’s doubtful that anyone mourned his death in season 4. This moment is doubly satisfying since this hated character finally gets what he well deserves, but also because those who are responsible for his death are able to escape without detection.
